上海电焊机厂的革命职工乘“九大”强劲东风,破除“旧框框”和“洋教条”的束缚,彻底改革老产品,成功地制造了硅整流直流弧焊机。它与同容量老产品比较,效率提高37%,重量减少三分之二以上,铜、矽钢片平材料节约二分之一以上,而且使用寿命长,维护保养简便,电流调节范围广,可以作为自动焊、半自动焊和手工焊的电源。
Shanghai Welding Factory revolutionary staff by “nine ” strong east wind, breaking “old box ” and “foreign dogma ” of the shackles, the thorough reform of the old products, the successful manufacture of the silicon rectifier DC arc welder. Compared with the same capacity of old products, the efficiency is improved by 37% and the weight is reduced by more than two thirds. The material of copper and silicon steel sheets is saved by more than one half, and the service life is long, the maintenance is easy and the current regulation is wide. Automatic welding, semi-automatic welding and hand welding power.
